The crisis of hope that afflicts the church today is a crisis of imagination. Catholic philosopher Peter Kreeft writes: Medieval imagery (which is almost totally biblical imagery) of light, jewels, stars, candles, trumpets, and angels no longer fits our ranch-style, supermarket world. Pathetic modern substitutes of fluffy clouds, sexless cherubs, harps and metal halos (not halos of light) presided over by a stuffy divine Chairman of the Bored are a joke, not a glory. Even more modern, more up-to-date substitutes—Heaven as a comfortable feeling of peace and kindness, sweetness and light, and God as a vague grandfatherly benevolence, a senile philanthropist—are even more insipid. Our pictures of Heaven simply do not move us; they are not moving pictures. It is this aesthetic failure rather than intellectual or moral failures in our pictures of Heaven and of God that threatens faith most potently today. Our pictures of Heaven are dull, platitudinous and syrupy; therefore, so is our faith, our hope, and our love of Heaven.
(Everything You Wanted to Know About Heaven)
If our pictures of heaven are to move us, they must be moving pictures. So go ahead—dream a little. Use your imagination. Picture the best possible ending to your story you can. If that isn't heaven, something better is. When Paul says, "No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love him" (1 Cor. 2:9), he simply means we cannot out-dream God. What is at the end of our personal journeys? Something beyond our wildest imagination. But if we explore the secrets of our heart in the light of the promises of Scripture, we can discover clues. As we have said, there is in the heart of every man, woman, and child an inconsolable longing for intimacy, for beauty, and for adventure. What will heaven offer to our heart of hearts?
